United States Patent DEVICE WITH NEEDLE AND CLAMPIN G MEANS FOR MATERIALStephen G. Cox, Westfield, N. J. Application April 30, 1952, Serial No.285,340

1 Claim. (Cl. 132-56) My invention relates to the placing of hairs,either of the real or synthetic variety, in the heads of plastic orrubber dolls. The method is also adaptable for the manufacture of wigs.

Heretofore many attempts have been made to insert hair in a dolls headso that the child can wash, comb, curl or dye the hair without successsince the rough treatment combined with the use of water causes the hairto become dislodged.

One of the methods used in the past consists of placing hair over thedolls head then punching through the head with a split needle. Thismethod is hit or miss and there is no certainty that enough hair will becaught by the split needle and forced into the dolls head, resulting inmany holes punched unnecessarily, some containing more or less hair andothers containing no hair at all.

One of the objects of my invention is to produce a head of hair on adoll which will be so firmly afiixed to the head that the hair may becombed, waved, washed or dyed without any loss of hair from the dollshead.

Another object of my invention is a method of producing a head of hairon a doll in such a manner that each stroke of a needle will positivelyemplace one or more hairs in the dolls head.

Another object of my invention is to produce a head of hair on a doll soemplaced that leakage into the interior of the dolls head, when the hairis washed, is impossible.

Other objects and advantages will be apparent from the specification anddrawings in which:

Fig. 1 is a partial cross section of a dolls head showing theemplacement of hair;

Fig. 2 is a cross section along 22 of Fig. 1 showing the needle andemplacement device inserting hair in a dolls head;

Fig. 3 is an enlarged plan of the instrument used for emplacement of thehair.

Referring to the drawings, 1 represents spools on which synthetic hair3, such as nylon, are wound. These spools are loosely and rotatablysupported on axles 4 mounted on a rack 5.

For the purpose of insertion of hair in the dolls head I provide ascissors-like instrument having a holder 6 which is partially cutthrough the middle to form a notch 7 and having hole 8 drilled from topto bottom to receive a hollow needle 9 whose shank is cut away at 10 tocorrespond to the notch 7 in the holder 6, the purpose of which will belater explained.

The holder 6 has an offset handle 11 and at the offset has an orifice 12pierced by a pivot nut 13 for the purpose of pivotally holding a handle14 carrying a stopper arm 15 slightly smaller than the notch 7 and beingfaced along its length by a strip of soft rubber or other suitablematerial 16. It will be seen that when the handles 11 and 14 are openedthe stopper arm 15 and facing 16 emerge from the notch 7 and when thehandles are forced together the stopper arm and facing enter the notch 7and cutaway 10 of the needle 9 closing off the hollowed portion of theneedle.

Operation As is seen by the drawings, the head of the doll 17 iscomposed of soft rubber to which I apply a coating of glue or shellac18, and preferably allow to set until the glue is tacky. Next it isnecessary to thread a strand of hair 3 from each of the spools 1 throughthe needles leaving a small portion of the hair protruding below theneedles. The handles 11 and 14 are now brought together so that thefacing material 16 is forced through notch 7 and cutaway 10 of theneedle clamping the hair 3 against the hollow needle side and holding itfrom vertical movement in either direction. The needles are now pusheddownward, unreeling hair from the spools 1 as they descend, and areforced tthrough the head material 17 and through the tacky glue 18. Atthis point the handles 11 and 14 are separated relieving the clampingpressure on the hair 3 and the needles are raised to a predeterminedheight above the head dependent on the length of hair desired and cut byscissors, knife or other sharp instrument (as shown by out line Fig. 1)after which the handles 1.1 and 14 are forced together and the operationrepeated until the entire head is covered resulting in a head of {Iranwhich will be irremovable after the glue or shellac as set.

It is entirely within the scope of my invention that the operation ofapplying cement and glue to the under side of the dolls head may be leftuntil the last step. since if rubber or soft plastic scalps are used,the pliability of the scalp will permit the withdrawal of the needlesand will retain the hair until the head has been covered at which time acement or lacquer may be applied to the under side of the scalp.

It will be understood by those skilled in. the art that many needles maybe banked on a single instrument so that one operation will implant manyhairs and that it is also possible to use twisted hairs from the samereel or hair from several reels each fed through a single hollow needleso that each puncture of the needle will implant more than a single hairat one time.

It will also be understood by those skilled in the art that I havedescribed a manual operation which by mechanical skill may be easilyincorporated into a machine to accomplish mechanically all of theoperations performed by hand.

Other variations in my invention may be made without departing from thescope of my invention.

I claim:

In a device of the character described, a vertically hollow needle, aholder for said needle, horizontally movable clamping means adapted tofit into a slot in said needle holder to interrupt the hollow in saidneedle, a movable pivoted arm attached to said clamping means wherebysaid vertical hollow may be obstructed or freed from obstruction bymovement of said pivoted arm to free or clamp material running throughsaid hollow needle for the purposes as described herein.
